Should I activate the Critical Update: "Require TLS 1.1 or higher for HTTPS connections"?

In Salesforce, you may have been prompted to activate the critical update "Require TLS 1.1 or higher for HTTPS connections" in your Salesforce org. Please do not activate this until all of your devices are on an Android version above 4.4.x. If you still have some devices on Android 4.4, they can continue to use TaroWorks as long as you are running TaroWorks 4.3.x or above. You will not be forced to do this update in your Production environment until July 22nd, 2017.
